Subject: Re: Subtracting regularly repeating sounds From: Jort Gemmeke <jgemmeke@xxxxxxxx> Date: Thu, 20 Sep 2012 07:19:37 +0200 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--e89a8ff249cf021e9b04ca1b4587 Content-Type: text/plain; charset=ISO-8859-1 Dear Kyle, I dont have experience with MRI scanner sounds in particular, but it seems like such a structured interfering source should be a good match for the exemplar-based source separation techniques I have been using over the past few years. You can find more information on my website, www.amadana.nl , as well as a demo (matlab) and some links to related techniques that may be of use. Feel free to contact me directly if you think this can be of use, then we can give it a try.
